The mechanisms of noise reduction nearly all result in artifacts of some sort, which a given individual would describe as distortion
Removing anything "unpleasant" from the RF off the antenna while surfacing a perfectly formed SSB audio which was formerly buried in the unpleasantness and totally unintelligible, or even so weak it was not noticed, is the holy grail of noise reduction. I've set right beside someone who called a signal "distorted" and I could not hear it. It's all in the ear of the beholder. Some recordings of the audio posted to a web page and linked from an email here would be useful. 73, Guy.
